Definitions

  • Present invention relates to production methods of parts with antimicrobial features of white goods such as cooling device and to production systems in which these methods are applied.
  • White goods such as cooling devices
  • These parts are used in forming such sections as body, door, and shelf of the white goods, and various applications are present in the state of art for these parts to gain antimicrobial features.
  • Antimicrobial material with various contents is applied on the surface of the part desired to have antimicrobial feature, preferably which can be in contact with food, by varied techniques such as dyeing, spraying and dipping, and accordingly the surface of the part gains antimicrobial feature.
  • the antimicrobial feature can lose its function in time. Additionally, it increases labor costs due to an external process applied after the production of the part.
  • Another application is the use of silver ions as described in published patent documents KR20040085322A and JP6023191A . However, silver ions have negative effects on nature in the process of recycling.
  • Production method developed by the present invention for the production of parts with antimicrobial feature which form various sections of white goods comprises the steps of fluidifying the antimicrobial material in particle form, which is silver ion-free, by mixing it with an oil; gathering the fluid mixture having antimicrobial feature in a dosage unit separated from a raw material unit in which a raw material mixture in particle form is gathered and from which the gathered raw material is fed into a mixing unit where the raw material is melted by being mixed; delivering the fluid mixture with antimicrobial feature gathered in the dosage unit to said mixing unit; mixing the melted raw material mixture coming from the raw material unit and antimicrobial mixture coming from the dosage unit together in said mixing unit; producing a part of white goods in desired form by the delivery of the obtained mixture to a molding unit.
  • Production system comprises at least one raw material unit in which the raw material mixture in particle form is added and which has at least one outlet; at least one mixing unit into which the raw material in particle form in the raw material unit is transmitted from said outlet and where said raw material is melted by being mixed; at least one molding unit into which the fluid in the mixing unit is transmitted to have the desired part form; at least one dosage unit which is in connection with said outlet and in which an antimicrobial material fluidified by being mixed with oil is gathered and transmitted from said outlet into the mixing unit so as to be mixed with raw material in the mixing unit at a certain proportion.
  • a white goods part each surface of which has the same antimicrobial feature, is able to be produced by providing the addition of the antimicrobial material to the raw material mixture in a fluid form. Additionally, through this developed method, parts which do not have any negative effects on nature are able to be produced in a cheap, easy and safe way by providing the use of an antimicrobial material which does not contain silver ion.
  • Objective of the present invention is to develop a production method for white goods comprising parts with antimicrobial feature and a production system in which this method is used.
  • Another objective of the present invention is to develop a production method which is able to be used in all molding systems by which the parts with antimicrobial feature are produced.
  • Yet another objective of the present invention is to develop a production method which is able to be used easily in all plastic production methods by which the parts with antimicrobial feature are produced.
  • a further objective of the present invention is to develop a production method for the production of the parts having antimicrobial feature without use of any silver ions and a production system in which this method is used.
  • Another objective of the present invention is to develop a cheap, easy and safe production method for white goods comprising parts with antimicrobial feature and a production system in which this method is used.
  • White goods such as cooling devices, comprise parts with antimicrobial features so as to prevent reproduction of microbial living beings such as bacteria, mold and fungus, in particular due to their direct contact with food.
  • These parts are used in forming such sections as body, door and shelf of white goods and preferably produced by various molding systems (such as injection, extrusion, blow molding etc.).
  • various molding systems such as injection, extrusion, blow molding etc.
  • silver ions are commonly used.
  • these silver ions have negative effects on nature in the process of recycling.
  • a production method applicable for the production of parts with antimicrobial feature, which do not contain silver ion, in order to form the various sections of white goods and a production system, in which this method is used are developed by the present invention.
  • Production method of the present invention is applicable for the use in various production systems (K), exemplary views of which are given in figure 1-3 , and comprises the steps of fluidifying the silver-free antimicrobial material in particle (generally granule or powder) form by being mixed with an oil preferably having petroleum content (e.g.
  • a raw material unit (1) in which a raw material mixture (together with the raw material, the mixture can also contain various admixture materials in granule or power form such as materials coloring the parts) in particle form (granule or powder etc.) is gathered and from which the gathered raw material mixture is fed into a mixing unit (2) where the raw material is melted by being mixed; delivering the fluid mixture with antimicrobial feature gathered in the dosage unit (4) to the mixing unit (2); mixing the melted raw material mixture and the antimicrobial mixture in said mixing unit (2) preferably homogenously and producing a white goods part in desired form by the delivery of the obtained homogenous mixture to a molding unit (3).
  • silver-free antimicrobial material in particle form is fluidified by being mixed with oil having petroleum content.
  • Fluid antimicrobial mixture is added to the molten raw material mixture at a certain proportion during the process of melting the raw material mixture by mixing. Because of the fact that both antimicrobial material and raw material mixture are in fluid state, preferably a homogenous mixture is able to be obtained and accordingly parts, each surface of which has the same antimicrobial features, are able to be produced. In addition, since the antimicrobial mixture does not contain any silver ion, the produced parts do not have negative effects on nature.
  • mixture with antimicrobial feature is able to be fed from the dosage unit (4) to the mixing unit (2) at a required proportion without the necessity for changing the raw material mixture in the raw material unit (1) and the part with antimicrobial feature is able to be produced.
  • feeding of the mixture with antimicrobial feature from the dosage unit (4) to the mixing unit (2) is stopped and production of parts without antimicrobial feature is able to be continued.
  • method of the present invention is easily able to be applied to all plastic production methods, which are currently in use and comprise a melting furnace for melting the raw material, by adding fluid antimicrobial material from the portion where the raw material passes to the melting furnace.
  • Production system (K) of the present invention comprises at least one raw material unit (1) into which raw material mixture (together with the raw material, the mixture can also contain various admixture materials in granule or power form such as materials coloring the parts) in particle form is added and which has at least one outlet (1a); at least one mixing unit (2) in which raw material in particle form in the raw material unit (1) is transmitted from said outlet (1a) and said raw material is mixed by melting; at least one molding unit (3) in which the fluid in the mixing unit (2) is transmitted so as to be formed as a desired part; and at least one dosage unit (4) which is in connection with said outlet (1a) and in which antimicrobial material fluidified by being mixed with oil preferably having petroleum content is gathered and transmitted to the mixing unit (2) from said outlet (1a) so as to be mixed with raw material mixture in the mixing unit (2) at a certain proportion (i.e. this proportion is %0,2 to %0,3 of the
  • Raw material mixture in power or granule form is fed from said raw material unit (1) to the production system (K).
  • Raw material mixture in the raw material unit (1) is transmitted to the mixing unit (2) so as to be melted and mixed for the molding process.
  • antimicrobial material which is fluidified by being mixed with oil preferably having petroleum content and gathered in dosage unit (4), is added to the raw material mixture in melted state in the mixing unit (2) by means of said dosage unit (4) at a certain proportion.
  • Raw material mixture and antimicrobial mixture are transmitted from the mixing unit (2) to the molding unit (3) by being mixed homogenously in the mixing unit (2).
  • Production of the desired white goods part is achieved in accordance with the molding technique (injection molding, extrusion molding and blow molding are illustrated in figure 1, figure 2 and figure 3 respectively) used in the molding unit (3). Furthermore, fluid antimicrobial mixture to be mixed with the raw material mixture by means of the said dosage unit (4) is able to be added to the raw material mixture at a required proportion without any interrupt in the production process, and accordingly production cost is able to be reduced.
  • white goods part each surface of which has the same antimicrobial feature, is able to be produced by ensuring the addition of the antimicrobial material to the raw material mixture in a fluid form. Additionally, through this developed method, parts which do not have negative effects on human health are able to be produced with a cheap, easy and safe method by providing the use of silver-free antimicrobial material.
